Digital sfigmographic system of high authenticity of pulse fluctuation registration PP243
The development concerns the diagnosis of the human cardiovascular system state, the monitoring and control of blood pressure and pulse rate, the readout of local and volumetric sphygmograms for solving the problems of polycardiogram and polysfigmography.
Main characteristics of development
Module of the measuring transducer: dynamic range - 0 - 300 mm Hg . ; basic miscalculation - not more than 0, 25% ; resolution is not worser than 0. 05 mm Hg; operating temperature range - 10 - 50 °С.
Sphygmographic system: number of channels - 4 . ; the possibility of choosing a single pulse fluctuation and its contour and spectral analysis; suppression of artifacts; the possibility of determining the index of augmentation and rate of pulse wave diffusion, determining the RR - interval variability; logging and creating a database of surveys; possibility of joint operation with electrocardiographs (within the polycardiogram complex).
Comparison with world counterparts , main advantages of development
The sphygmography system is different from the existing analogs («VaSera - 1000», Japan, «"Complior - 01», France, «VICORDER», Germany) using a precision piezoresonance sensor of a new generation with modulation of the inter - electrode gap of resonator excitation, which provides a higher resolution when measuring air pressure at the level of 0. 05 - 0. 075 mm Hg. This provides new possibilities for parameters determination of pulse fluctuation and allows to detect the pathologies of the cardiovascular system of the human in the early stages. It significantly increases the diagnostic value of the existing procedures.
The sphygmography system can be used in medical institutions and diagnostic centers for the diagnosis of the health of the cardiovascular system and the detection of symptoms of the pre - infarction and pre - stroke conditions of a person separately (for example, the "Home Physician" device) and integrated into the "Cardiologist's workplace".
The state of development
The experimental design was made. The draft documentation was developed. The expected characteristics were confirmed.
